How Kamloops is built

Kamloops's houses by when they were built Ten house shapes, one for each tenth of Kamloops's 32,450 houses. Before 1961: 11%, 1961–1990: 51%, 1991–2000: 15%, 2001 or later: 24%. Older houses glow hotter.

Each house stands for one in ten of Kamloops's 32,450 houses (single-detached, semi-detached, row and duplex), drawn by when it was built. The glow shows the usual pattern: older houses tend to be leakier and less insulated. Snowfall scales with heating degree-days.

Why the design temperature matters in Kamloops

−17.8°C is the 22nd-mildest design temperature of the 70 cities we cover. The F280 calculation works out how much heat each room loses on that design day, from the house's actual walls, windows, air leakage and ceiling insulation.

At −17.8°C, a cold-climate heat pump sized to the calculation can carry most of the season, and the number shows how much backup heat the coldest days need.

In the Kamloops area, 83% of households heat mainly with a forced-air furnace; natural gas is the main heating energy for 90% of households (Statistics Canada, 2023).

Why skipping it costs money

Contractors who size by square footage routinely oversize. An oversized heat pump costs more to buy, cycles on and off, dehumidifies poorly in summer and wears faster. An undersized one leans on backup heat. The F280 report is the evidence either way, and it's worth having before you compare quotes.

What it costs

About $150–$400 as a standalone calculation (a September 2026 planning range; quotes vary). Many energy advisors bundle it with an EnerGuide evaluation, which also gives the calculation measured air-leakage data instead of an assumption.

NRCan-licensed service organizations serving Kamloops

Many energy advisors also do room-by-room CSA F280 calculations for an extra fee; HVAC designers do them too. Ask for the F280 report itself, not just an equipment recommendation.
